Sorry to be asking this because I'm not really into chess. However, this is my dad's passion and since Father's day is coming up, I want to buy him the best chess software there is.
In this regard, can you help me out. I've been doing some research in google and some say that the best is Deep Sjeng, some say its HIARCS, Shredder, Fritz12 while others say it's Rybka. I don't know who to believe anymore.
Can you guys please point me to the right direction. How can one know if this is the best chess program? Is there any official tournament between chess programs or a website that ranks them? I want to print the website
that shows the program as the #1 chess program in the world and attach it to the DVD chess program i'm going to give my dad on Father's day.
Thanks in advance.
Here is a website where you can print the list:
http://ssdf.bosjo.net/list.htm (hasn't been updated with Rybka 4 yet, but as you can see, Rybka 3 is at the top)
it confuses me sometimes in reference to time control and hardware :)
IMHO Chessmaster would be the best program for an amateur because of the features it offers, a strong engine with different levels and chess video tutorials to help an amateur to improve the game. Now, if you are a serious chess amateur with aspiration of becoming a very strong chess master, then Rybka would be one of the choices among other chess engines. Please note that there are free non commercial chess engines which are very close to Rybka chess strength, such as Stockfish 1.7.1. Therefore, you probably would do best to spend your money with a good chess tutorial program for your father and get the free non commercial chess engine.
Just a word of warning if you are about to buy Rybka for him. If you buy it from the Rybka site in the UCI version he will not be able to run it without some extra software as the UCI version just does the chess "thinking" stuff without any user interface or for that matter opening book.
You can get freeware for the user interface but as it is a present I would suggest you buy a version that comes with a user interface (assuming it fits your budget).
The main options are Rybka+Aquarium from http://chessok.com/shop/index.php?main_page=index&cPath=7_1
and Rybka+Fritz style interface from http://www.chessbase.com/shop/productlist.asp?product=cp&subd=&user=&coin=
Note also that there are:
- normal single processor versions which will only ever run one processor core,
- and "Deep" versions that will run on single core PCs but will take advantage of multiple processors if you have a dual or quad core PC.
Its just a cost difference and obviously the Deep versions play better if you have an appropriate PC.
Atypical rating lists:
http://www.tomteipel.de/info-1.html - #1 (Deep Rybka 4 x64 2981)
http://www.inwoba.de/bayeselo.html - #1 (Deep Rybka 4 2949)
http://www.compchess.de/html/elostat.html - #1 (Rybka 4.0 x64 1CPU 2980)
http://sedatchess.110mb.com/index.php?p=1_58 - #1 (Deep Rybka 4 x64 3273)
No need to mention CCRL or CEGT - their prominence as testers is self-evident.
Need I say more?
>> No need to mention CCRL or CEGT - there prominence as testers is self-evident.
Can you elaborate?
Is there any meaningful distinction between Deep Rybka SSE42 x-64, Deep Rybka 4 x-64 and Rybka 4 x-64?
The two gentlemen before me, as you stated, did the honors.
Thus, there is no need for redundancy. Indeed so, there's no need to shame the names that brought you guys the fame to your claims.
so if u want style rather than hardcore elo mania,i rpefer stockfish 1.7.1 and komodo 1.2
rybka 4 is the strongest chess -engine-, but if you dad is not serious about analyzing positions & games, it's very much a luxury & not a necessity. if he just wants to play it for kicks to say he got whupped by the strongest chess program, that's fine (though junior is more likely to make his head spin while he goes down in flames). and keep there are probably at least a half dozen free engines that would demolish any human & most of them provide pretty good to top notch analysis as well. if he's more into training or playing with the idea of competitive games, there may be better options.
for a gift to your father, for a chess software, you can not consider only the chess engine ( like schredder, fritz, rybka, hiarcs, etc etc ) , but you need also to consider the GUI ( graphic interface) , like aquarium, chessbase, schredder...
every interface need some pratice, to master all the functions...
for the moment if your father has no chessprogram, you can choose GUI chessbase or aquarium on DVD very nice... schredder is only for download.
you can only consider chessmaster , the engine " the king" is not the best , but only GMI can win against it ... and the gui chessmaster is very nice for the beginner's chessplayer.
after 261 games played, Rybka 4 is only 5 ELO stronger than Rybka 3 !
So for me the purchase is worthless !!!
It was 3min blitz games with ponder off and no Large pages.
In all testings I did, It was between 5 and 28 ELO stronger than Rybka 3.
Also it only seems that R4 is performing better when using 8 cores or maybe more....
Despite that, I had more similar results to the independent testers like CEGT and CCRL than the Rybka beta testers.
So why do we have this difference, is unknown.
But it is there.
PS: what should be the current conclusion ? No or few bugs but unstable results ?
To summarize my fustration which may have been written too much here :
Rybka 1 to 3 are Rolls Royce/Meteorites within computer chess
Rybka 4 is very disappointing as strengh is supposed to be the main focus of Vas.
That said, I will keep my eyes open to what happens on the market as others are now closing the gap.
Thanks for your answer and clarification.
OK, so what ever is wrong on my computer and CEGT/CCRL, this is not related to Rybka scoring better on 8 cores or more.
But it is still TBD.
This is now understood after Lukas comment.
What is now to explain is why does beta Rybka testers have different results than official organizations testing engines and also many other customers.
Also they don't use all new features of Rybka like large pages and SSE4.2. In my tests I also use a set of 117 GB tablebases. Rybka can take advantage of that, Stockfish can't.
One is that the default time management settings aren't best for "movestogo" time controls. This was the results of a bias in our testing.
The second is that we dropped contempt by default. This was a necessary step which will give us a one-time ding on the rating lists.
the only possible thing i can think of is rybka 4 really takes advantage of breadth with 8+ cores, maybe due to some discovery w/ cluster code, which is said to have a very broad search. but again, in my tests with 12 cores this wasn't the case. moves were found @ similar depth across h/w spectrums.

Rybka 4's search is slightly "broader" when more cores are used. More cores will win in fixed-depth tests, for example. It's a small difference, though.
Computer chess fans should always tell you this. It is strange that someone says Hiarcs is best - even Hiarcs fans should be a little critical to realise that their positions is not on the top.
